摘　　要：在云存储服务中,为了让用户可以验证存储在云存储服务器上数据的完整性,提出一种支持动态更新和公开验证的云存储数据完整性检测方法。通过引入双线性对和用户随机选择待检测数据块可以无限次验证数据完整性是否完好无损;可信第三方的引入解决了云用户与云存储供应商在数据完整性问题上产生的纠纷,实现数据完整性的公开验证;然后给出该方法的正确性、安全性以及性能分析,最后通过实验验证了该方法是高效可行的。In order to allow users can always verify the integrity of the data stored in cloud storage server, this paper proposed a cloud data integrity detection method with dynamic updating and public verification. Users could infinitely verify whether data integrity was intact by introducing bilinear pairings and user randomly selected data blocks to be verified. Trusted third party auditor （TPA） could solve disputes of data integrity between users and cloud storage provider to realize the integrity of the data public validation. And it analysed the correctness and security of this method. Finally it verified the proposed method that could detect cloud storage data integrity by experiment.
